MSI’s interactive HPC resources are composed of some of the same systems used to support our batch scheduled HPC activities. The main difference between the two services is the way in which users interact with the MSI resource. Interactive HPC systems allow real-time user inputs in order to facilitate code development, real-time data exploration, and visualizations. Interactive HPC systems are used when data are too large to download to a desktop or laptop, software is difficult or impossible to install on a personal machine, or specialized hardware resources (e.g., GPUs) are needed to visualize large datasets. User input might come through a command line interface (i.e., system shell) while debugging a piece of software or through mouse clicks while using a program with a graphical interface.
Unlike MSI’s other computing options, the Interactive HPC resources are designed only to be used in real time for tasks such as interactive data exploration, creating plots or images, visualizations, or testing sections of code that will be used on other MSI systems.
Common use cases include:
- Testing a compiled program at the command line before submitting it as a job
- Developing code or exploring data in an interactive environment like MATLAB, IPython, or Rstudio
- Visualizing data or building simulations in applications like Schrodinger, COMSOL, or Avizo
srun: Submit an interactive job on the current HPC system to provide a command line or graphical interface to interactively run software.
Open OnDemand: Preferred way to access MSI HPC clusters via a web browser, which can be used to set up a graphical environment, run applications, and use interactive development environments. Supporting Jupyter Lab, Rstudio, and more.
Jupyter Notebooks: A web portal for notebook-based computing in the browser, which can be used for reproducible and shareable data analysis, visualization, and scripted control of larger tasks. Currently supports Python 2, Python 3, and R.
CITRIX: Citrix for Windows Environments: Connects a user to a graphical Windows environment, where they can access specialized Windows software for modeling and data analysis.
NICE: No longer supported at MSI, if you used NICE previously please switch to Open OnDemand for your interactive environment work.
- NX NoMachine: No longer supported at MSI, if you used NX NoMachine previously please switch to Open OnDemand for your interactive environment work.
